Phone not charging? Battery or charging port: how to tell

A phone that charges slowly, only at an angle or not at all usually has one of two problems: a worn battery or a damaged charging port. They look similar, but the signs are different.

Signs of a worn battery

• The percentage drops fast or jumps from 30% to 5%.
• The phone shuts off even when the screen says there is charge left.
• The phone gets hot while idle or the back looks lifted.

If the case looks swollen, stop charging the phone and bring it in. A swollen battery should not be used.

Signs of a charging port problem

• The cable feels loose or only works when you hold it at an angle.
• Charging starts and stops by itself.
• You can see lint or dirt inside the port.

Quick checks before you book

1. Try a different cable and a different wall adapter.
2. Restart the phone.
3. Look into the port with a torch. Remove loose lint gently with a wooden or plastic pick, never metal.

If it still does not charge, a technician can test the port and the battery. See our repair services or book a home visit and we come to you.
